Hi, I was trying to upgrade my system from SP2 to SP3. I mounted the SP3 image on PowerIso and started the upgrade process. But the installation errored out and said it is not able to find presetup.cmd and setupORG.exe files. I searched for txtsetup.sif file. I found two of them; one with and without the following lines: presetup.cmd = 1,,,,,,,2,0,0 setupORG.exe = 1,,,,,,,2,0,0 As per the previous discussion in the link mentioned below, I added these lines on the second file and restarted the system. But the installation is still not continuing; everytime on restarting, the system is trying to restart the installation and failing. I also tried by starting in safe mode but no luck. Presently, I am able to boot in through linux and then access internet (the system is dual boot). Does anybody pls. know how to overcome this problem. I will either like to roll back to SP2 or continue the installation to get SP3. Also since I can see two txtsetup.sif files, have I loaded windows over windows or something like that. Thanks, Emma Good.
