Does not work in 64-bit Windows

[imaginationac]

I haven't been able to use Compile AHK on my Windows 7 64-bit machine. I've done numerous test cases to check file permissions, as well as testing compiling with the standard ahk2exe. On 32-bit Windows XP, I have no trouble.

The error message I get when compiling is: Error: Error opening the destination file.

If anyone with 64-bit version of Windows could confirm this, I'd appreciate it.

This is where it probably fails.

The script copies the compiler to a temp directory in AppData. I check the command that's run and nothing seems to be apparently wrong.

I decided to do a clean install of Autohotkey_L and Compile AHK to the default install location instead of the custom location I had. And it seems to work. Now to figure out why.
