My Corel Draw 9 quit working after installing DoubleCAD XP Pro3. The Corel splash screen would get to "Almost Done..." then Windows installer would start and try to install Windows Office XP Pro, then bug out.
This was verified by uninstalling DoubleCAD, which then caused Corel Draw 9 to work again.
My OS is Windows XP Pro.
This is odd behaviour, it seems that the two programs are conflicting with each other!
1. UN-installing DC and clean up the registry.
2. Delete the 'roaming data' file as well - by - typing in the windows search field %appdata%, open the 'Roaming' folder and totally delete the IMSI folder. This will be rebuilt on a fresh install of DC!
3. Re-install DC again - but this time to a new directory (folder).
*Test this out and see if this brings you anything different.
