MSI (c) (10:E0) [17:37:07:981]: Product: Microsoft Office Excel Viewer - Update
'Microsoft Office Excel Viewer 2007 Service Pack 1 (SP1)' could not be installed.
Error code 1625. Additional information is available in the log file

Steps taken to resolve this issue-

There may be an invalid past reference in the registry to Excel viewer here:

[HKEY_CLASSES_ROOT\Installer\Products\00002159F30090400000000000F01FEC]

"ProductName"="Microsoft Office Excel Viewer 2007"

Points of interest -

1. The product name for the current version of the Excel viewer should be:

"Microsoft Office Excel Viewer"

2. There are no other values under

"HKEY_CLASSES_ROOT\Installer\Products\00002159F30090400000000000F01FEC". Only the

ProductName.

If we delete the key

HKEY_CLASSES_ROOT\Installer\Products\00002159F30090400000000000F01FEC, and reattempt the Excel Viewer 2007 install, it succeeds without the bogus Policy error.
