Paintshop X (10) will not start after installing X4

[Burning Sky]

Although I like some of the features of X4, I hate others. None-the-less, I've tried everything to get PSP-X to open to no avail. PLEASE HELP!!! I NEED PSP X!!!!!

There shouldn't be any problem installing multiple version of PSP on your computer, I myself have version X2 to X5 and I can use all of them. During the installation, did you specify to install other the PSP X folder under your Program files folder or how did you install PSP X5 on your computer?

I also have PSP8 X2, X3, X4 and X5 coexisting on my computer and apart from recognised bugs they all play nice with each other.
X2 and X3 share the same user folders for scripts etc. but others are independent.
