Baidu on the internet a bit, mostly said the following methods:
Open IE and select [Tools]/[internet Options] from the menu to enter the Internet configuration interface. SELECT [Programs]/[Manage add-ons] to view the currently loaded ActiveX situation.
When you see that the Bhomanager class is present and its status is "Disabled", click "Enable" to turn on this feature and save and exit to resolve the issue.
When the Bhomanger class add-in is not found in the admin add-in, if you install QTP, the C:\WINDOWS\ System32 there will be a dynamic link library called BHOManager.dll, or you can search for BHOManager.dll directly on your computer, and then view its path. Load this DLL by clicking [Start]/[Run], enter CMD, and navigate to the directory where the DLL is located, and type the regsvr32 BHOManager.dll command to register the DLL. Problem solving.
I found that my add-on was not a problem, and then my workaround was to run QTP as an administrator, and then the recording would be fine.
QTP When recording scripts, the script content is empty
