Purchase/upgrade has bugs and can make the application unusable The application works great, but I've had trouble with the program upgrading. I used the free version without issue, then I purchased it and it won't work. Gives me an error and I can't uninstall the original free version. I've been a web developer for over 20 years so I'm highly experienced with installing programs, etc. It's been so annoying that I'm considering finding another solution and taking the purchase of wsftp as a total loss, because I have to have something that works. I've done some research and this is not an isolated issue. There are work arounds posted, so far no luck, but a good product would not require work arounds. It's a shame because the product works great, just your purchase/upgrade functionality is flawed.

Great product with many useful… Great product with many useful features. Service support is also exceled and very proactive in their investigation. I'm sure that we keep using their great product range in many years to come.

Complete scam I purchased their software online and never received my serial number. Then sumbitted my information on their sales and support forms and heard nothing back. Then called the number and was on hold for 26 minutes before they just said "our offices are now closed" then got kicked back to the main menu.

Worst tech support I have ever… Worst tech support I have ever encountered. Takes an act of congress to reinstall and activate software after a crash. They say to call tech support to get it reactivated but then say you can't contact tech support without a support contract.

Does not display properly on 4k Windows 10 The app on windows does not display properly in 4k which is the only real choice for my laptop where I need to run it. I have been a loyal customer for over 20 years and now I'm being told that there is no fix for the problem and no estimated time for a fix to go into place. I feel really let down. Now, I hear that IpSwitch has been bought out and I have not received a response what they are going to do about my problem.
