Today, I have just encountered a weird problem with my VS2013. I wanted to add another toolbox but the “Choose Items..” dialog wouldn’t show up. It was taking forever to load it. So, I googled some information related to this problem. And finally, I ended up in this post.
I never thought that InstallShield Limited Edition on my VS2013 could cause such trouble. However, after uninstalling the InstallShield LE, the problem was solved. So, for those people who are having similar problem and have an InstallShield LE on VS, try to uninstall the InstallShield LE. I hope it solved the problem.
