Im found a bug in the product VMware.ThinApp-5.2.7 .After comparison snapshots , it a copy files project to the folder I specified.but during copying files project write can not save the project, no directory found.because the folder name has the long name is this folder, or in Russian. Why your product VMware.ThinApp 5.2.7 not incompatible with the program image line fl studio pro. Well it does portable version fl studio pro. But does not start portable version image line fl studio pro.
Build process can have some issues with longer folder names or certain characters used. You should be able to edit the build bat file to rename the program so when building it doesn't have any issues etc.
