Getting File corrupt or DIsk space error while upgrading
Issue : Getting "File corrupt or Disk space error" while upgrading OpManager.
Solution: This could be due to unavailable space on the drive where OpManager installed , if that is not the case , if Operating system's 'Regional Options' is not set to English(United States), change it to English and try to upgrade again.
(Start --> Control Panels --> Regional And Language Options --> Change the Regional Options as English (United States). --> Click Apply and OK button)
After upgrade you can revert the changes.
Note : This might also happen if you try to upgrade without "Run as administrator " option. Go to OpManager directory through command prompt with " Run as Administrator " and try the upgrade steps.
