The installer takes 30 seconds (or more) to appear
Check to see if the computer has access to the Internet. The MSI files are digitally signed. This signature is verified during installation. Windows also checks to see whether the certificate used to generate the signature has been revoked. This requires Internet access, but will time out after 30 seconds.
Possible solutions are:
- Allow this to happen. This does not affect the installation other than to delay by the time out period.
- Connect the computer to the Internet.
- Re-sign the MSI with your own key. Use one that is trusted by the computer, and does not need to access the Internet to find the certificate revocation list (CRL).
