CtrlX Works 1.20.8 could not install adaption package.

[Brant]

I just installed ctrlX Works 1.20.8, when I want to install add-ons through Add-on Installer, all the packages will fail to install with the error below:

There are two ways to install add-ons in the previes version, when you click Add-on installer in Tools, a Windows warning will tell you Add-on Installer will boot and if you click yes , add-on installer will load and if you click no the previes installer will load. 

But now, seems only the new installer is available because when you click on Add-on Installer, there is no Windows warning untill you select a package to install it.

So how could I install package now or this is a bug that need to fix?

The add-on installer could install package again with out any changes, just after a holiday and when I try to install it again, the package could install successfully. Don't know why. May be a reboot of computer is required by that time?
