Can't uninstall

[amapic]

Hi,
I can't uninstall clawPDF 9.2 and 9.3. I tried to solve this with the program MicrosoftProgram_Install_and_Uninstall.meta and it doesn't work (it correct registry error and others). I installed it with the msi installed in an other msi. It is of course linked and it doesn't come from clawPDF but do you have any idea about how to solve this ?

Thanks for your help
