Starting with the ITMS 7.5 SP1 release (with SIM 7.5.240 and later), there is a new reboot check message:
"Another installation is requiring a reboot to complete changes to the system...."
To skip the pending reboot check, use the following regkey (key is not created by default):
Create a Key called "IgnorPendingReboot", with DWORD value name as Enable and set the values as mentioned below.
•Enable = 1 Ignores pending reboot
•Enable = 0 Checks for reboot
