First I install Coreldraw GS 12 the I decided to update it to Corel X3 but my PC begun to slow then I uninstalled the X3 and try to reinstall the CGS 12 but it won't let me it saz error in applying... :confused:

Are these legal, pruchased copies of this software? Have you re-booted and tried the uninstall again. How are you un-installing? From the Corel uninstall link or from Control Panel (Remove Programs options)? Have you contact Corel support?

As far as I know its legal because I purchased it from a software shop... I already used both ways to uninstall it but same it saz error applying transforms...

In addition I already used force uninstall, now the problem is it still in my add/remove program but there's no options (change / remove) and I can't reintall it...
