I am trying to install a new software package. The installer fails with a 1720 error. I have successfully installed a few other products lately, so I suspect this is a bug in the installer with this particular product, so I have written to hahaSupport... Yet, googling for this error shows that it may be a Microsoft problem after all with a broken InstallShield installation. My XP Home Pro system has all the normal updates installed. Any idea where to look? Thanks!
