Error 1722 is a generic MSI installation error and doesn't accurately reflect what the true error is. To find out what the actual error is we'll need to review the FlashInstall.log file(s) from an impacted system. Depending on the error a verbose MSI install log file is also requried. Providing both now will be helpful. Please do the following:
- Run the MSI installer from the command-line and generate a verbose log file with additional debugging enabled (log options = v+x)
- When the error is returned click 'OK' to close the error dialog
- Close out of the MSI installation dialog window
- Locate the FlashInstall.log file on the system:
- 32-bit OS: C:\Windows\System32\Macromed\Flash
- 64-bit OS: C:\Windows\System32\Macromed\Flash AND C:\Windows\SysWOW64\Macromed\Flash
- both files are REQUIRED from a 64-bit OS
- Upload the FlashInstall.log files(s) and the verbose MSI log file to cloud.acrobat.com/send using the instructions at How to share a document
- Post the link to the uploaded files in your reply
