HP QualityCenter/ALM is normally run through InternetExplorer (as it doesn't work in any other browser). However if you are using a recent version of IE, your (not completely recent) HP ALM installation may simply refuse to work.
This howto assumes that you have admin privileges on your PC and that you know how to use a cmd.exe.
ALM can be run in an IE independent window using ALM Explorer 'Add-In'. Go to
https://hpln.hp.com/page/hp-alm-explorer-addSearch the "Downloads" section and download the "Add-in". Be sure to download the version that matches your ALM release!
This will install the folder
C:\Program Files (x86)\HP\HP ALM Explorer xx.xx\
The client side installer does not create shortcut or Start menu entries. So you will need to do that yourself. Also most users have problems unless they run ALM-Explorer as adminstrator.
If you get a warning that capicom.dll is missing, go to the next section.
If you get the warning Main application process failed to start, you may have data from a newer or older version. Delete the following folder:
C:\Users\YOUR_LOGIN_NAME\AppData\Local\HP\ALM-ClientAppData is a hidden folder, so make sure you have Show hidden files enabled.
If ALM-Explorer complains about missing capicom.dll then
Goto Start->All Programs->Accessories right click Command Prompt choose Run as admnistrator
msiexec /a Downloads\capicom_dc_sdk.msi /qb TARGETDIR=c:\CAPITMP
Now quit and restart ALM-Explorer and try to access the server again (this SHOULD work without a reboot).
