windows 7 compiling problem

When I modify an indicator in metaeditor and hit compile, I am getting the message "Access is denied".
What do I need to do, with xp I didn't have this problem.

Metaquotes have completely messed up their file structure when it comes to Vista and Windows 7 compatibility. Fortunately MT5 addresses the problem properly.

By for the present problem. The file was probably downloaded and now can't be changed. What I do is download files then create a new indicator and copy and paste from the downloaded file. I thought the problem was a read only file buy the properties weren't set.

install MT4 into another folder. Don't install it in "c:/program files", make a new folder somewhere else and install MT4 there and all problems will go away.

"c:/program files" is read only and MT4 tries to write in this folder which is not allowed under any circumstances. This was already problematic on windows XP but most users ran XP as admin user so the problem did not trigger.

MT4 simply cannot run in "c:/program files/" the way it was designed, it is using the 15 years old folder layout from windows 95. It seems they didn't know about the existence of windows 2000 or windows XP in Russia by the time MT4 was developed or they simply couldn't afford anything else than their old windows 95 PCs.

starting metaeditor will solve your problem, i got the same too...

rightclick on MetaEditor.exe --> properties --> compatibility --> check "Start as Administrator"

hope you'll find it

This is not a solution! Don't give such fundamentally wrong recommendations!

Installing it in another directory is a solution and solves the problem.

A solution that only hides the symptoms while leaving the problem unchanged and even introduces new problems can never be a solution, especially not if an easy and proper solution to the problem is available.

Running something as admin is almost never the proper solution to any such problem. Fixing the problem is the solution.

Other alternatives:

One can turn off UAC (User Account Controls) to grant read/write access to all folders. Maybe not so good from a security point of view. Start->UAC.

One can grant the user read/write access to the metatrader folder
or
Grant all users read/write access to the metatrader folder and thereby switch of folder visualization. Open a cmd window and:
cacls "c:/program files/<metatrader directory>" /t /e /g everyone:F
cacls "c:/rogram files/<metatrader directory>*.exe" /t /e /r everyone

One can give the user ownership of the metatrader files & folders

While there might be some truth in this statement (regarding many other things that happen in and with windows) this particular issue is not a windows problem. Windows behaves absolutely correct here and MT4 is completely wrong. There cannot be any doubt who is to blame for this bug.

Do you by any chance own a large block of shares in Microsoft?

When you install MT4, you have the option to install it any any directory you choose. I don't see how this could possibly be described as a bug. Most br0kers assume that their clients will want to follow the convention of installing software under c:/Program Files, and set the default accordingly. But the client is at liberty to overtype this (see screenshot).

What I find unacceptable is that Microsoft restricts the directories in which I may write or update files. That is not a bug, either, but I see it as being unnecessarily draconian, even though I'm pretty sure that I understand their reasons for it.

You are of course welcome to differ. We have disagreed on issues like this before.

i'm trying hard to think of any trading software that does not by default install under programs.....

esignal, metastock , metatrader, and seems like both worden and ensign all installed in programs.....

'metastock data' is the only thing trading related on any machine here with me now not in the programs folder....

this might extend well past the russian borders..... maybe it's a world wide software folder conspiracy......h

No, I hate this company from the bottom of my heart. But I have to admit that certain things are now finally done the correct way and this is one of them.

No, this is a bug. The default setting of the installer is wrong for an application that behaves this way. Either Metatrader is meant to be this way, then the installer is wrong (by giving an unusable default or failing to set folder permissions as it needs them) or Metatrader is really meant to be installed in "program files" then the bug is in metatrader because it tries to write inside its install folder which is generally unacceptable.

If it doesn't work with default settings then this is considered a bug by all known standards of software engineering, the default settings are not usable.

This has been this way in Windows since Windows NT and Windows 2000, over a decade ago and it has been the standard in all other multi-user operating systems for half a century already. This is standard behavior!

And there is absolutely no need for a program to ever have write access to the program folder. There is a folder for program files and there is a folder for user files. Its all in perfect order. User files belong into the user folder, program files belong into the program folder and everything works.

User A does not have access to the files of user B unless access is explicitly granted and following this old convention c:/program files belongs to the admin user and is read-only for all non-admin users, just like its equivalent /usr/ is owned by root on other platforms and users can only read and execute but not write there. Because the user never has any need to write there during normal operation, only during program installation!

And since YOU are the owner of the PC you have the admin password, you can log in as admin at any moment and change the file and folder permissions to your liking and write to wherever you want if you wish. The folders don't belong to MS, they belong to admin and since YOU are the admin (unless you work on someone else's PC) your statement does not make any sense. It is admin who restricts or grants file permissions, not MS. I don't see how MS is bad for giving you an OS with the ability to do this and shipping it with reasonable default permissions for admin and user.

You spoke of conventions regarding "c:/program files", this is a convention, a very old convention even, older than many people in this forum, older than Microsoft and the "c:/program files" folder itself. And it was certainly not invented by MS, MS just did not implement it the proper way for a long time, only recent versions of Windows are slowly beginning to behave as one would expect it from a multi user OS and what is already standard everywhere else.

MT4 should conform with this old standard, other programs don't have any problems putting their files into the places they belong , MT4's failure to do so is a bug.

No, its only a small number of programmers who have not yet realized that on modern and complex operating systems there must exist certain conventions of what belongs where and that these old conventions are now being enforced by the OS (and rightly so) to not let the chaos prevail.

It didn't really come as a surprise, these conventions were introduced to windows with windows 2000, only the enforcement of these conventions has been very lax for the last 10 years and I think this was a long enough time for every programmer to fix his broken code.

They must fix their programs and change a few folder names here and there because Windows isn't very likely to change the folder structure back to utter chaos and anarchy only for these few buggy programs who want to abuse the installation folder for things it was never meant for. This abuse will not be allowed any longer, these programs will stop working.
