I tried the wine cmd.exe command and it runs. But trying to run the .bat file got this: Z:\Users\Jkirk279\desktop>run PSDK-FULL.bat wine: cannot find L"C:\\windows\\system32\\run.exe" File not found Hmm. I ran winecfg. I got "failed to connect to the mount manager" in the X11 Drives dialog window. Does this imply Wine's not emulating the drive tree correctly ? If the installer can't find the run.exe command then I doubt any DOS commands will run. I hope there's a suggestion to test that. Maybe there's a way to reset wine ?
