Product:
Planning Analytics for Excel (PAX) version 35
CORREDIST_version=CORREDIST-AW64-ML-RTM-11.0.35.13-0
CORREDIST_name=IBM Planning Analytics for Excel
Microsoft Excel 365 64 bit Version 1803 (Build 9126.2336 Click-to- run)

Problem:
After installation of PAX on Windows 7 with Office 365, you only can get PAX add in to work if you start Excel as “Run as Administrator”. If you start Excel as normal user you are missing the add-in “IBM Framework for Office”.

Suggested solution:

If you can not manually add the COM Add-ins, you can create a file and add below values to registry on client computer:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ClickToRun\REGISTRY\MACHINE\Software\Classes\CognosOffice12.Connect]
@=”Connect Class”

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ClickToRun\REGISTRY\MACHINE\Software\Classes\CognosOffice12.Connect\CLSID]
@=”{0e159c85-c989-4582-8208-3d2afa48c15a}”

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ClickToRun\REGISTRY\MACHINE\Software\Microsoft\Office\Excel\Addins\CognosOffice12.Connect]
@=hex(40000):
“Description”=”IBM Framework for Office”
“FriendlyName”=”IBM Framework for Office”
“LoadBehavior”=dword:00000003

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Excel\Addins\CognosOffice12.Connect]
“Description”=”IBM Framework for Office”
“FriendlyName”=”IBM Framework for Office”
“LoadBehavior”=dword:00000002

You can save above in NOTEPAD, name the file addvalues.reg. Then if you double click (to run it) on it it will add the values to registry on your computer (if you have the rights to do so).

How Check NET framework

To find .NET Framework versions by viewing the registry (.NET Framework 4.5 and later)

1. On the Start menu, choose Run.
2. In the Open box, enter regedit.exe.

   You must have administrative credentials to run regedit.exe.

3. In the Registry Editor, open the following subkey:

   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full

   Note that the path to the Full subkey includes the subkey Net Framework rather than .NET Framework.

   Note

   If the Full subkey is not present, then you do not have the .NET Framework 4.5 or later installed.

   Check for a DWORD value named Release. The existence of the Release DWORD indicates that the .NET Framework 4.5 or newer has been installed on that computer.
