Program plugin doesn't work

[kubalav]

Program plugin doesn't show result in latest version. I tried clean installation.

[taooceros]

Could You please upload the log so that it will be easier to debug?
Maybe try reindex in program plugin setting?

[kubalav]

I tried reindex.

Let me take a look, but I think if there is only two program that is unable to load, other programs should be loaded successfully.

[kubalav]

It doesn't work at all.

[taooceros]

Would you try open Flow with Administer Authorization? One of the log suggests Access denied.
I have just checked the win32 indexing and it works for me.
By the way, is any UWP app can be loaded?

[kubalav]

I runs Flow with Admin access. I see UWP app only, not win32.

[taooceros]

Let's try clicking this button and see what we get.

[kubalav]

UWP only from C: drive

Hey @kubalav how's it going, can you see if previous flow version has the same problem for plugin?

Also are you able to boot into windows sandbox and try?

I am away from comp most of the day, will take a look at your log later.

@kubalav I think this error block the All function to create index. So,maybe try to remove E:\ from program file source and reindex?
But why does that throw?

I tried Window Sandbox a few times. I tried new WS config (without shared folders) and Program plugin works. I copied this portable version to normal computer and changed index path to Program Files. Not working.

[kubalav]

@taooceros I kept Program files only, no success.

[taooceros]

I copied this portable version to normal computer and changed index path to Program Files. Not working.

Well, I don't think the program plugin need to include index path to Program Files for working. I have tried portable mode in my computer, and it seems working correctly.

Sorry for the troubles, but could you please update the logs without E:\

[taooceros]

I think I found the potential reason of why one single exception may block the whole index from creation. It maybe cause by the use of IEnumerable, which contains the characteristics of lazy processing, so the try catch within each sub index method doesn't catch the processing error elsewhere?

Let me change the indexing contruction of program plugin a few, and check whether it is because of that.
