This is sort of a stress test of the Add-on Store trying to download a lot of add-ons.

Steps to reproduce:

• Start a brand new NVDA (no personal config)
• Open Add-on Store
• Install all the add-ons starting with letters "T" and "U"
• Control+tab forth and back to leave the "available add-ons" tab and turn to it
• In the "T" or "U" add-ons, there are add-ons reported as "Available" (strangely); install them again

Actual behavior:

First, it is strange that add-ons that have been installed are available again when turning in the "available add-ons" tab

Second, I get a CRITICAL error in the log. NVDA does not freeze nor crash, but I guess a CRITICAL is quite worrying in any case.

Expected behavior:

First the add-ons that have been installed should all appear as Downloading or pending install.

Second, no CRITICAL error should occur.

Does the issue still occur after restarting your computer?

Not tested

Have you tried any other versions of NVDA? If so, please report their behaviors.

N/A

If NVDA add-ons are disabled, is your problem still occurring?

N/A, but no add-on initially installed since the STR uses a brand new config.

Does the issue still occur after you run the COM Registration Fixing Tool in NVDA's tools menu?

Not tested, unrelated.
