Strange Error Starting Abaqus 6.12

[CedricFr]

Hello All,

I am writing this message because I've just reinstalled my Abaqus 6.12 on my computer (Windows XP x64 SP2) and at the end of the installation in spite of having "test x passed" I have a blank window and after that when I'm trying to execute the program a prompt appears with the following message : "The system cannot execute the specified program"

Have you any idea of what can be wrong ?

P.S: I've installed this version of Abaques a several times on other computer and everything goes fine...

Thanks in advance.
