From: Claire on 28 Jun 2010 13:27 Hello, I am not sure what I am doing wrong. The fact is that I cannot recreate the problem on my computer, one of my users is struggling with. The problem is that on his computer app crashes with: "Run-Time error '75': Path/File access error" message. I have traced this problem to the point app wants to create folder in: C:\ProgramData\<my app title> That path is obtained using GetSpecialfolder(CSIDL_COMMON_APPDATA) Interestingly, I cannot recreate that crash on my computer. User has Vista Business (32 bit), with Administrator privilages and UAC is on. I have also noticed another strange thing about that Vista. It returns False to IsWinNT4Plus function: ============================ Function IsWinNT4Plus() As Boolean Const VER_PLATFORM_WIN32_NT As Long = 2 Dim osv As OSVERSIONINFO osv.OSVSize = Len(osv) If GetVersionEx(osv) = 1 Then IsWinNT4Plus = (osv.PlatformID = VER_PLATFORM_WIN32_NT) And (osv.dwVerMajor >= 4) End If End Function ============================ Any comments and your help appreciated, Claire

That folder is off limits in those conditions, except for setup apps running with admin privs. It's just like HKLM. http://visualstudiomagazine.com/articles/2009/01/19/lemme-tell-ya-where-to-stick-it.aspx > I have also noticed another strange thing about that Vista. > It returns False to IsWinNT4Plus function: > ============================ > Function IsWinNT4Plus() As Boolean > Const VER_PLATFORM_WIN32_NT As Long = 2 > Dim osv As OSVERSIONINFO > > osv.OSVSize = Len(osv) > If GetVersionEx(osv) = 1 Then > IsWinNT4Plus = (osv.PlatformID = VER_PLATFORM_WIN32_NT) And > (osv.dwVerMajor >= 4) > End If > End Function > ============================ > > Any comments and your help appreciated, Which test is failing? First thing I'd change is the test for GetVersionEx return.

Karl, what is wrong with that folder: C:\ProgramData\<my app title> ? It is listed on the webpage you provided link to. If that folder location is wrong which location will be safer? I need the location for all users. Thanks, Claire "Karl E.
