Hi.
I have a problem with my installscript project.
I need to call the "SHGetKnownFolderPath" function but when I build the project there's no error in build. So, I test the build but when this takes some part of the installation then an error appears: "error in call "SHGetKnownFolderPath".

Please, Anyone to help me?, thanks.
P.D. This is the error code:
Error Number: 0x80040707 Failure to call the function

I haven't yet had to make that particular shell function call, but based on other such ones, you need to at least change all of the SHGetKnownFolderPath references instead to SHGetFolderPathA to match the available ANSI function--like you also indicated in your comment.

thanks for reply and happy new year taco.
OK, I modified the script and when compiling only one error was reported:
comma expected in 0hff325c4c9dbbb043b5b42d72e54eaaa4
but this is the reference when define the constant so whats the problem?

Well that new compile error is because that FOLDERID_SavedGames value appears to be a hexadecimal value, so it needs to be preceeded by "0x". However, according to the KNOWNFOLDERID documentation, it should actually be a GUID value of "{4C5C32FF-BB9D-43b0-B5B4-2D72E54EAAA4}".
Also, I looked into it further and that newer SHGetKnownFolderPath function call surprisingly doesn't have ANSI & Unicode counterparts, so you can ignore my previous suggestion.

Understood.
I looked MSDN documentation too and yes I need to set that GUID value but when you define this GUID value you need to enclose with quotes?

No, you do NOT need to enclose the GUID value when defining it which should also satisfy the calling funtion.

But a GUID with curly braces and dashes is not a NUMBER, right? I don't have a solution, just want to point out that you may need to adjust the prototype.

Oh, and SHGetKnownFolderPath requires Windows Vista or above. If you also want to support XP you'd better call SHGetFolderPath which takes an INT parameter (CSIDL) to specify which folder you want to retrieve http://msdn.microsof...1(v=vs.85).aspx

Okay, after re-reading the original post I noticed that you are looking for the saved games folder, which was introduced in Vista, so my previous comment about XP is obsolete

Thanks for suggestion about to support XP Stefan, I'll take in mind.
The first parameter in the prototype is NOT a number (you're right) because string variables passed to DLL functions are passed by reference. In that case I need to use that type of value: "BYREF STRING"
But when compiling there are errors related to character "{", unreconized character, etc..

For the GUID to be a string you must include the "" in your define.
Maybe try and assign the contant to a variable, like this:
#define FOLDERID_SavedGames "{4C5C32FF-BB9D-43b0-B5B4-2D72E54EAAA4}"
szSavedGames = FOLDERID_SavedGames;
and then use szSavedGames in the first parameter.

Thanks for your help, now the compiler not reports any errors. But when I install the product then an error is report like this:
Failed --> the system can not find the file specified.

I think the problem resides in the final parameter...

Based on the error message, I would think the problem is the first parameter, still something wrong with that GUID. Did you run ProcessMonitor from SysInternals to see which file it tries to access?

Hi.
Yes, so this is the result from Process Monitor... and only is filtered with file system activity and only setup.exe process.
I attached the image from process monitor but it seems the error points to a diferent path

So it actually doesn't try to access the path. Not sure what to recommend next.
You could try writing your own DLL to call the function, and then pass the result back to InstallShield. This would also help to find out if the problem is in InstallShield or in the parameters for the function call.

Yep, so this not try to access but for xp this work well. I think the only problem is in the parameter.
I'll try that, thanks.

It works on XP??? XP doesn#t have a saved games folder, so it shouldn't work on XP at all.

Sorry for my bad explain... In XP, I use this Knowledge base to take a path from a subfolder of Public folder as a reference:
