Excel Trying to Load PowerPivot Add-in (version 11.1.3129.0) for Excel 2010 even after Uninstalltion of the Add-in.

Question

Hi all,
I am trying to Package and deploy Powerpivot Add-in for Excel 2010. I have the Powerpivot_X86_(11.1.329.0) .MSI which installs Unattended, but Uninstallation will not remove entry from COM ADD-IN list in Excel and at first re-launch (even after
Power Pivot Uninstallation) it will try to load Powerpivot add-in and will give an error.
Downloading file.///c:/Program files (x86)/Microsoft analysis services/AS Excel Client/110/Microsoft.AnalysisServices.XLHost.Addin.VSTO did not succeed.
this above path is the [InstallDir] which gets wiped off with the unistallation of the .MSI. So, before uninstallation,I stop the excel process and am running a script to delete HKCU Add-in Reg key entries.
and also, I thought it may be implicitly loading the add-in from folder such as,
C:\Program Files\Microsoft Office\Office14\XLstart
%appdata%\Microsoft\Excel\XLSTART
but nothing is installed there.
Second Issue
when I re-install,
it doesn't automatically show up in the Excel ribbon (even after reboot and even if regeistries are created at the same location) but instead we should add it through COM ADD-IN list in Excel Manually.
Appreciate any idea's and suggestion's.
P.S
is it possible to make it completely installed per system rather having user entries?

Answer 1

Guys, I think I solved the
issue:
Symptoms
1. Power Pivot SQL 2012 32-bit installed over the old version without
deinstalling it
2. Installed with a user with administrator rights
3. It worked under the profile with admin rights, it didn't work under the
normal users w/o admin rights and threw this error message: Downloading file.///c:/Program files (x86)/Microsoft analysis services/AS Excel Client/10/Microsoft.AnalysisServices.XLHost.Addin.VSTO
did not succeed.
4. In the admin profile, it went to the path "110":  C:/Program
Files (x86)/Microsoft Analysis Services/AS Excel
Client/110/Microsoft.AnalysisServices.Modeler.FieldList.vsto
5. In the normal profile, it went to the - wrong - "10" path:
C:/Program Files (x86)/Microsoft Analysis Services/AS Excel
Client/10/Microsoft.AnalysisServices.Modeler.FieldList.vsto
SOLUTION
1. ADMIN: Installed VSTO 4.0
2. ADMIN: Checked if the .NET Programmability Support was installed - it was -
if not, install it!
3. NORMAL USER: Create a .reg file (Backup your registry before!) and
use it UNDER THE NORMAL USER!!!
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Office\Excel][HKEY_CURRENT_USER\Software\Microsoft\Office\Excel\Addins][HKEY_CURRENT_USER\Software\Microsoft\Office\Excel\Addins\Microsoft.AnalysisServices.Modeler.FieldList]
"Description"="Microsoft SQL Server PowerPivot for Microsoft Excel"
"FriendlyName"="PowerPivot for Excel"
"LoadBehavior"=dword:00000003
"Manifest"="C:\\Program Files\\Microsoft Analysis Services\\AS
Excel Client\\110\\Microsoft.AnalysisServices.XLHost.Addin.vsto|vstolocal"
"CartridgePath"="C:\\Program Files\\Microsoft Analysis
Services\\AS OLEDB\\110\\Cartridges\\"
4. NORMAL USER: Rename the registry key
"HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\User Settings\Microsoft.AnalysisServices.Modeler.FieldList"
into
"HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\User
Settings\Microsoft.AnalysisServices.Modeler.FieldList_old"
5. NORMAL USER: Start up Power Pivot and it should
work now!
Analysis
IMHO the issue lies in the fact, that the Power Pivot
installer creates two problems:
The first issue is that the path to the add-in under
the NORMAL user is simply wrong and points to a wrong location (the
"10" in the path). In the admin profile, where it was originally
installed, it points to the "110" path which is correct.
The second issue is that the installation procedure
somehow needs to create a registry key (the one under point 4 in the solution)
to complete it self and if this key already exists it fails to install and
throws up weird error messages. If you delete or rename this key, it is created
again (exactly in the same way) but then everything works out.
Hope this
helps!
