I'm still running Quicken 3.0 for Windows. It was designed to run under Windows 3.0. Yes, it's a very old program, but it does what I need and I don't want to spend the money to upgrade it.
Without Avast! 4 Home (the free version), QW.EXE and the Quicken installer program (install.exe) run just fine under Windows XP SP2. As soon as Avast! is installed, neither qw.exe or install.exe will launch. I have even tried disabling avast! (but leaving it installed), and they still do not run. As soon as I uninstall avast!, they run.
This took me some time to figure out as I uninstalled various programs one by one and tested qw.exe after each one. After installing avast, it worked. Then I reinstalled all the applications one by one. qw.exe worked after each one, until I installed avast!. Then I reinstalled and uninstalled avast! 3 more times, and every time avast! was installed qw.exe would not execute and everytime it was installed, it stop working.
avast reports no viruses. This is a new install of the OS. I have a firewall and spybot running. Even running qw.exe in compatibility mode does not work when avast! is installed. But when uninstalled, qw.exe runs just fine, even without compatiblity mode.
Other programs run just fine. Other installs run just fine. So far, it appears on the quicken executable and install program are somehow blocked. No errors are reported, nothing is in the avast! log, qw.exe and quickens install program, install.exe just do not start. Any ideas?
