I have win 7 professional 32 bit, graphic card GTX 550 Ti. The program starts to load and then shows the man and backgound and then shows ipisoft has stopped working. Previously I had had it on my other drive which was win7 pro 64, however I had to do a clean install of the os. I want to take the licence back to the reinstalled 64, but it will not let me without deactivating in the 32. I may have to do an unisatll in the 32 os and then deactivate. So while I have written this, I managed to unactivate it on the 32 OS after a clean install of ipi studio. Hope this does not happen in the 64 OS.

Loaded it on my 64OS, no problems - I opened and closed it about 5 times. I think I know why the problem occured with the other 32 OS. When I had fitted the new card GTX 550 Ti, windows found the driver, I could not be bothered to update with the new driver from nvidia, however with the 64 OS i updated the driver from Nvidia site. Maybe that is the solution. However i will update the driver in the 32 OS when I have a bit of time.

So it seems it is working fine.
