Question:
I get the error message "This installation package could not be opened. Contact the application vendor to verify that this is a valid Windows Installer package" when I try to un-install/re-install Tekla Structures. What causes this and what should I do to fix the problem?

Answer:

The error you get might be caused by several reasons, for example:
  • you do not have administrator rights to the computer
  • you did not start the un-installation/re-installation in "Run as administrator" mode
  • the original installation package has been damaged in the temp folder below the user's profile
  • the downloaded installation package is damaged, or the download was not completed properly.


Please try these steps to troubleshoot the problem:

1. Try to re-install Tekla Structures by right-clicking the installation package and selecting "Run as administrator".

2. Verify that the installation package you downloaded is complete (of correct size), for example:

  • Tekla Structures 20.0 64-bit installation package: 376MB (394 657 792 bytes on disk)
  • Tekla Structures 20.0 SR1 64-bit installation package: 251MB (263 806 976 bytes on disk)
If you are not sure about the size, try downloading the installation package again and re-try installing as an administrator after that.

3. If you have not got administrator rights to your computer or sufficient access to the installation folder/installation package, please contact your system administrator.
