I had been using Wizip Pro 15.5 (purchased from Amazon as part of the Corel Paintshop X4 package) and was quite satisfied with the performance. A marketing email from Corel invited me to upgrade to version 17 Pro for the bargain price of £12.95. Installation was OK but the performance of my PC slowed dramatically. The culprit seems to be ZipSend which upon installation integrates itself as an add-on to Outlook (you have no choice). Outlook now took up to a minute to load (previously a few seconds) and became virtually unusable, producing various error messages when sending emails. There is no facility to remove ZipSend. I therefore decided to remove Winzip 17 pro (and revert back to 15.5) - that was a chore! There is no uninstall facility with Winzip 17 and using Add/Remove in Control Panel produced a failure of the removal half way through and I had to re-install 17 the go through the whole uninstall again. A final clean-up with RegClean Pro was required to get rid of related registry items. Very disappointing.
