My first question is, are you certain the 32-bit is the correct version? You can check this a few ways, but the fastest would be to do the following:
Hit Start
In the search bar, type in dxdiag and hit enter
It will ask you if you want to validate certificates or some such. The answer to that doesn’t matter in this instance.
On the System tab, you will find what operating system you are running. If it says’64-bit’, then you may have the wrong version.
If this is not the problem, there are a few other things to check. First, do you have any other firewalls in place? Windows Firewall is not the only firewall that can be running. Sometimes, third party Anti-virus programs such as McAfee or Norton also have a firewall. Check those as well. You may have to write a firewall exception to open specific ports. For more information on which to open and how, check out the following link:
You can install the 32 bit version of SU in 64 bit win too (e.g. you need it if you want to use plugins like Sketchyphysics which only work with the 32 bit version), or are there differences in the license?
There shouldn’t be a license difference. The license should work across all OS platforms that Sketchup supports. That said, I have run across quite a few programs that don’t work with a version outside of what the computer can handle. It may be a hardware issue, or it may be an OS issue. Either way, whilst I am unsure about how Sketchup works in terms of compatibility with each OS, I have run into various programs that will ONLY work with the OS version that you have (i.e. 64-bit vs 32-bit). If you are able to install the 32-bit version, I would look to the ports in the firewall, and make sure the correct ports are open.
I stopped Kaspersky, deleted Macfee, shut down windows firewall, and opened all ports for SkeTchUp, and I surely online, because I could use this forum, I feel I’m naked running on the internet just for SketchUp, but “Add License” button reminded me offline all the time.
What did it mean? When I tried the last try-reinstall SketchUp. It asked me why I selected to uninstall it, I selected"It doesn’t perform well". This is my real feeling. Since I couldn’t connect to the SketchUp team, I want anyone here could connect to them transfer this info to them.
“Add License” function is really a problem, I found others have met with the same problem, it shouldn’t be so sophisticated even for payed user,
