The latest working version for me is build 9009. Update to 9200 failed. Clean installation of 9205 failed.
Going back I noticed I couldn't delete files because the paths were too long (patch folder). I was installing in root (E:\ServiceDeskPlus-MSP). So I did all I could to keep the paths short. I think the structure of the program folders is absurd. It should be possible to stay within the limit of 259 characters.
I believe my installation problems are also due to long paths. I guess I will stick to 9009 for the near future and switch to another program in the long run. I can't spend days fiddling around to get this running. That's too bad because until now I was quite satisfied.
I use Win10 64-Bit.
