ERROR_INSTALL_SOURCE_ABSENT 1612 The installation source for this product is not available

ERROR_INSTALL_SOURCE_ABSENT 1612 The installation source for this product is not available. Verify that the source exists and that you can access it.

Hello. I have a question about this error: ERROR_INSTALL_SOURCE_ABSENT:  Contact your technical support group. This is System Error 1612. I have an MSI package which works on all installations, but occasionally on an update or uninstallation this ERROR 1612 happens.

I think on almost all installations where this error happens it would not copy into the cache directory. How do I avoid this error or improve my setup so that this error wouldn’t happen any longer?

Thanks!
