Activesync installation error: Windows could not complete Activesync installation

14 Mar

Posted by Abdul Aziz as Troubleshooting, Windows Mobile

This one’s for Eudora email client users. While installing Activesync 4.1 for the first time, you may get the following error:

Microsoft ActiveSync: Windows could not complete the installation as it was interrupted. Cancel<>Finish

This happens because Eudora email client uses its own version of mapi32.dll. To resolve this problem, open Eudora.

1) Go to Tools—>Options—>Mapi—>For Use Eudora Mapi Server select “Never”
2) Rename the Mapi32.dll file from “C:\Windows\System32″
3) Open Outlook and do a Detect and Repair
4) Goto Tools—>Options—>Other and check “Make Outlook the defualt program for E-Mail, Contacts and Calendar.

Now try installing Activesync 4.1 and it should install successfully.

I had the same error messages, had Eudora 7.0 set to always use MAPI, renamed MAPI32 as Remove_MAPI32 launched Outlook (I don’t use it yet) and it prompted me to fix a problem (guess it was fixing MAPI32… it did the trick (Eudora was running all this time) and the install worked… shame I can’t sync my SPV M600 with yahoo calendar :(

I had the same problem with ActiveSync 4.1 and 4.5, even though Eudora wasn’t running at the time. Followed the suggested fix and 4.5 installs perfectly. Thanks!

All you need to do is make Outlook your default email program……

You don’t need to make outlook your default program if you don’t want to.
I had the same problem and after reading this thread, I simply went in C:\WINDOWS\SYSTEM32\ then renamed MAPI32.DLL as MAPI32_EUDORA.DLL (to keep a copy). I then had a MAPI32.000 (previous version prior to Eudora installation), I renamed as MAPI32_OUTLOOK.DLL (just to save a copy and then copied it to MAPI32.DLL.
Thereafter the installation worked. All that time Eudora was on (but I did not use it) with MAPI still selected as Always use.
I then copied back MAPI32_EUDORA.DLL onto MAPI32.DLL.

Oops, sorry, remove the “I then copied back MAPI32_EUDORA.DLL onto MAPI32.DLL.” from my previous message. otherwise ActiveSync does not launch. Anyway Eudora still works with original MAPI32.DLL.
