Missing msihelper.dll when uninstalling ExpressCache

After upgrading from windows 8.1 to 10 I noticed my ReadyCache SSD is no longer working.

I am tried to uninstall the ExpressCache and ExpressCacheApp. Only successful uninstalling the ExpressCacheApp. Having missing msihelper.dll error when uninstalling ExpressCache.

In my Windows.old I am no longer have the Condusive or Sandisk folder to restore to my current Program Files folder.

What should I do?

I cant use the SSD anymore

contact sandisk support. they have a beta removal tool they can send you and you can try that and see if it will fully uninstall the app. after that reinstall should work.
