Uninstalling Rational Software Architect v6.x on Windows XP

When uninstalling IBM Rational Software Architect v6.x under Windows XP you may receive errors and be unable to complete due to the lengths of the file paths. This is covered in the following support article on the IBM web site

The answer, for me, was to use the subst command from a command prompt and map a drive to a folder within the directory tree. This problem is due to the highly nested structure of the folders within the installation locastion and therefore the subst command has to be peformed at a level which is at a sufficient depth to avoid this problem. For me the following was sufficient.

C:\ subst U: "C:\Program Files\IBM\Rational\SDP\6.0\updater\workspace\proxies\eclipse\features"
C:\ rmdir /s updater.rwd_shared.plugins.6011.ifix001_1.0.0

This allegedly only affect those installs which have had the v6.0.1.1 update applied.
