Good suggestion! I will try installing SetupBuilder on the XP test machine. I am continuing to check to see if any Windows settings on that machine might be causing a problem. The install is built with the latest SB 8 version. Additional info: 1)SetupBuilder is running on a 64 bit Windows machine. 2)The "Type Of Install" setting is 32 bit. 3)The install that fails on XP is a "single file" type install. 4)We also produced a Web Install version, loaded the required files to our web server, and placed the 244K EXE file on the same XP machine. It ran perfectly. Only the "Single EXE file" type install produces the error.

I will report back after implementing your suggestion.
