Couchbase 2.1.0, 2.1.1 freeze on upgrade on Windows

Hello. Earlier I've tried to upgrade my couchbase from 2.0.1 to 2.1.0 and installation process stuck at "Computing space requirements" at the end of installation. Then I was unable to do anything with install and killed install process. Then I reinstalled couchbase - all good, except all data was lost. Now I've tried to upgrade 2.1.0 version to 2.1.1 and got the same problem.

* After install process termination couchbase windows service is not installed. May be there are some problems with installing that service.

* In windows logs MSI installer writes that "Couchbase Server -- Installation operation completed successfully." But when I try to use some utils from bin folder I get such error:

C:\Program Files\Couchbase\Server\bin>ip_addr.bat
Could not load module C:\erl5.8.5.cb1\erts-5.8.5.cb1\bin\erlexec.dll.

And erl5.8.5.cb1 floder is inside C:\Program Files\Couchbase\Server\, not C:\

Cluster configuration: One Windows x86_64 server, 35Gbytes free on HDD.
All services that access couchbase were stopped before upgrade.

« Back to question.

Before upgrade, please shutdown any browsers such as explorer, firefox and chrome. It is possible that some window runtime libraries are used by these processes and Couchbase installer tries to check and update files.
