Error installing v1.21

When I try to install v1.21 on NopCommerce 3.4, I receive the following error:

Cannot insert the value NULL into column 'UseStaticFileName', table 'MisterL.dbo.FNS_FeedRec'; column does not allow nulls. INSERT fails.

Download new version from our site.
Replace all files from archive (.sql from Install folder too.)
Restart your site.
Plugin will upgrade itself.

We have added new property for simple migration from Froogle (NopCommerce).

Read this link  about the new feature.

Hi,
I want to install plugin(1.34) but i get this error Must declare the scalar variable "@feedid". Must declare the scalar variable "@feedid".

please help.

Did you see the error during installation?

I think I found the bug. You use case-sensitive database mode.
Download new version from our site and try. We changed SQL script. I'll be wait for your answer.

thanks
