In some cases when installing Patch1212 IRRICAD might ask for the IRRICAD.msi file and/or the installation disc. This may be caused by a broken cache of the original installation, a missing file in your IRRICAD folder, or a re-named IRRICAD folder.
In some cases installing Patch1204 first allows Patch1212 to install successfully. Download Patch1204 from http://www.irricad.com/Irricad/Download ... ch1204.exe and install before installing Patch1212.
If this does not help uninstall IRRICAD via the Control Panel - Programs and Features (Windows 7) or Add / Remove Programs (Windows XP) and reinstall the full Pro Version 12 and then Patch1212 from http://www.irricad.com/irricadpro/irric ... e-upgrades . If you have an existing IRRICAD folder (e.g Irricad Pro 10) remember to change the installation path to this folder during the installation wizard to retain the previous path settings.
