6"The detection failed, this can be due to a temporary upted installation database."What should I do?

A: Check your directory % windir % \ installer. If there is not much content left in it, we recommend that you uninstall your program, reinstall it, and patch it step by step, until the version you need.

If you manually cleared the % windir % \ installer directory, if you still have a backup, copy the original file back, install the patch, and try again.

If only one or two MSPs are lost, they may be repaired, Which is troublesome.

If you do not want to reinstall it, try the steps described in the "references" Article below.
