InstallAware

We have InstallAware Studio X10 and used it without a problem for years. Now suddenly every time we're trying to build a release, any release, either from the IDE or from command line using miabuild.exe we are getting the following error:
[exec] Created Windows Installer database
[exec] Built installation executable
[exec] Injected setup languages
[exec] Error during build: Unable to build runtime files: Archive handler not installed
[exec]
[exec] Build failed

This is happening to all the developers in our team (2 of us)

Any help, suggestions would be highly appreciated.

It looks like a corrupted installation.

Do you have any third party Anti virus installed? Did you update it recently?

I tried to uninstall and re-install InstallAware but the error persisted.
I'm sure the company i work for has some Anti Virus installed on all our machines. I'll ask if it has been updated recently.

Thanks Francesco, it was the company anti virus. Once they rolled back the update InstallAware started working again.
