Cannot run the big size exe file (>900MB) on Windows Storage Server 2003 x86 SP2 OS(Hyper-V VM machine)

When I run a big size exe file(>900 MB) on Windows Storage Server  2003 x86 SP2 OS VM mchine(which is managered by Hyper-V server), I got the following error message:

Windows cannot open this program because the license enforcement system has been tampered with or become corrupted.

This setup.exe should be a trusted source because of it run other OS(windows 2003, windows 2008, 2008 R2 etc.).  we use the same way to create the exe whose size < 700MB, it works fine on the same machine(Windows StorageServer 2003 x86 SP2 OS VM machine).  So I assume that the file size(>900MB) causes the problem, It seems that OS dont' support it.

My questions:

1. Is there the limitation of exe size to run on WindowsStorage Server  2003 x86 SP2 OS VM machine?  If yes, what is the size of limitation?

2. What reason is this error? Is it related with Hyper-V?

Thanks,
