just perform the installation procedure on the machine that has the BTCS?
Yes, but before that make sure that the client is closed. Your block chain will be overwritten.
And also it will be nice, if you will make backup of your block chain and upload it for analysis.
Just open
%APPDATA%\Bitcoin directory and make copy of
blk0001.dat and
blkindex.dat files.
This should be done before the block chain will be overwritten. Be careful with the
wallet.dat!
