{Issue Resolution – 300th post!}CRM 2015 Outlook plugin fails to install – Currently unsupported version is Internet Explorer 0

First of all, this is my 300th post on this blog!


Now back to topic at hand:

CRM for Outlook is one of big differentiating features for Dynamics CRM in the CRM segment of products.

Sometimes though it can lead you into issues into undocumented territory. I was trying to get CRM 2015 for Outlook installed during analysis for one of my clients on Outlook 2010 with IE 11 installed on the machine.

Surprisingly, the installer will not install. On tracing, I found the following error:

11:57:11| Error| You cannot use a version of Internet Explorer that is earlier than Internet Explorer 8.
11:57:11| Info| Currently unsupported version is Internet Explorer 0.


The thing with CRM is whenever you think you have seen lot of weird issues, it brings something to the screen which is unchartered territory.

We have IE 11 installed with a supported configuration for CRM 2015, still the error is saying that IE version is less than 8, on tops Info log says that it is 0.


Ok, my digging started for Solutions. I saw solutions like this one:

· Repair Office: Didn’t work for me and also for people in community

· Reset Internet explorer: Didn’t work for me and also for people in community.

Issue Resolution: Here is the solution that worked:

Go and locate the following Registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Version = in my case

Check the value for HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Default

This might be blank, copy the value from Version into this key value and restart your machine.

Try installing Outlook Client for CRM again, issue should be resolved now.

Hope it helps and Happy CRMing as usual!
