If UAC (user access control) is enabled, then Vista won't allow a program to write .exe's into the 'Program Files' folders after the initial installation has completed.
You can either:
1) Install blitzmax in a folder other than somewhere under your program files tree
or
2) Store your source files somewhere different (Which will still break the included helpfiles in the Blitzmax documentation, you can't compile & run those from within the IDE either)
or
3) Disable UAC
