Vista - Directory where my software is installed must permit write access

I have been using Vista and like it. All my software loaded file except on
program the error message appeared:

"Please make sure the directory where program is installed permits write
access"

I went into properties of the C drive and check write access but error
message still occurred.

Any suggestions?

Which program in particular is giving this error?

The issue is created because the software was probably created originally for Windows XP (or an earlier version of Windows), for which full read/write access was granted to the Program Files and Windows folders.

In Vista, the default security settings, including for Administrators, are to only allow write access to the "Program Files", "Program Files (x86)" and "Windows" folders when installing an application. This has broken several applications that have not been written according to the proper guidelines, which states that any settings the program may need should either be stored in the current user registry, or in the current user profile AppData folder.

You should contact the software supplier to determine if a Vista update is available that addresses this issue.

Until then, you can try running the application in XP Compatibility mode:

1. Right-click the shortcut to the program, and select Properties
2. Click the Compatibility tab to open it
3. Check the box for "Run this program in compatibility mode", then selct "Windows XP (Service Pack 2)
4. Click OK

That *might* resolve the problem, but your best bet would still be to get updates for the software to make it work properly in Vista.
