[Ham-Computers] InstallShield Problems.

[KD7JYK DM09]

The OS is Windows XP.

Suddenly I am unable to install from a .exe or uninstall programs.  I get an
InstallShield error 1607 which has to do with a missing or corrupt
ISShield.msi file.  There is no trace of it on the computer.  Following
various instructions on microsoft and other websites does not help, so far
no information is accurate, files names, locations, et cetera.

How can I get InstallShield to work again?  Where can I get it from and just
re-install this program?  My wife spoke to a co-worker, one of the computer
geniuses for the state and he said he has heard of the problem before and
the best bet is to reformat and restore the HD, why can't InstallShield just
be put back on and use as normal?
