I'm just setting up a new Windows 7 box as an experimental upgrade to our usual Windows XP and Linux/Ubuntu environments. Windows 7 Ultimate (64 bit) Visual Studio 2008 Standard SP1 (C#, C++, and VB) InnoSetup installed FS Git installed to C:\freeswitch I'm not trying to do a setup build yet, just a standard build. However, I'm having problems with the JSON library. It compiles Ok under XP, but gives VBscript errors under 7. The only thing difference I can think of that might be relevant is I have VB6 installed on the XP box, but I doubt that's actually required for VBS. At line 135 of the script, it's trying to create a .bat file in the directory. The only thing I can think of is that maybe the random number generation isn't as random as one would like, resulting in it re-using the same script name and running into a "file exists" type of problem. Any suggestions?
