Hi, I'm using VerGetFileVersion to determine the version of a file on the target system. (Installscript-Project). Problem: under Windows-Vista, this function returns -1 and an empty version string. According to the Installshield documentation -1 is no valid return value of VerGetFileVersion. It seems that the problem has nothing to do with UAC - it occurs on either activated and deactivated UAC. How can I determine the version of a file under Windows Vista? H.
The path string of the file had quotation marks "c:\...". This worked fine on OS's other than Windows Vista. In order to apply the VerGetFileVersion-function on a Windows Vista OS, the path string has to be without quotation marks.
Thanks for posting this. But what a nightmare having to find out that THIS peculiar function behavior was the probable cause of things hanging in an IS2008 installer on Vista.
