I have the following problem concerning an uninstallation after a major upgrade:
- I install a dll with a product X (built with Installshield 11.5) In the registry the Shareddll counter for the dll = 1
- I do a major upgrade of the product X (new product version built with Installshield 2009) In the registry the Shareddll counter = 2
- I uninstall the product --> the dll already exists In the registry the Shareddll counter = 1
The shareddll counter explains why the dll isn't removed during the uninstallation. But why this count is egal to 2 after the major upgrade? This problem doens't exist if I use the same installshield version for buid the two major versions. So, it's seem it's a issue between IS 11.5 and IS 2009...
I need to find a solution: I have to do with Installshield 15 a major upgrade of a previous version built with Installshield 11.5. The uninstallation of this new version has to be correct. Do someone have a solution for this problem of counter? Thanks
This could be caused by two separate components (meaning two components with different component codes) installing the same file. The existing component gets a share count, and the new one also gets a share count, resulting in the behavior you are seeing. You may try the following: - Ensure the component codes of the component(s) containing these file(s) do not change between releases. - Ensure you are completely uninstalling the old product and then installing the new one (this option in in the Upgrades view under Upgrade Windows Installer Setup).
