I installed 2 different versions Siemens 3000 Manager E on a new IBM Thinkpad with Windows 7. At first it worked fine, but noticed I couldn't browse to the KDS folder, seemed like it was hidden. I fooled with some folder settings with no luck, de-installed Manager E, did a system restore to the day before, re-installed and changed save options to a new folder. Originally I got "Error writing Kds", now after downloading 100% I just get the spinning cursor, the only option is to close the program. Maintenance works ok, it seems like it just can't create and save the kds file.
