Service Center Update Problems

Hi All I'm running Win 7 64bit Cakewalk Platinum with the latest updates.
I first installed Komplete 10 from Disks then upgraded to Komplete 10 Ultimate from external HD.
What happens when I go to update program-(s) within the Service Center it will download the update that's fine, It's when I go to install the update it starts and goes through all the steps to update the program and just before its done I get a error message that the update can't find a valid program (missing the .msi) it stops the update and instructs me to re-install the original program. The Service Center then removes the program from my computer. This has happened with Absynth, Kontakt, FM8 and Komplete Kontrol. I'm afraid to do any updates as it's a major issue re-installing the programs. Any Ideas???

 

Besides using Service Center you can also download the latest updates from the download area (after you login with your account):
