How to convert PDF to BLOB datatype

@srikanth999, package management is not always straightforward. You will need to unzip the archive from my post above. You may have to try several folders or sources before it works.
It appears you have not installed UiPath.Script.Activities.

  1. See ddpadil’s link regarding package management, and the post below it.
    2( There may or may not be a ‘packages folder as shown’:
    “C:\Users\<username>\AppData\Local\UiPath\packages”. Try to put the packages in there, and find one that works when you install it.
  2. However, you may get the package from nuget (see ddpadil’s post) after you configure your sources, and then it may show up in C:\Users\\AppData\Local\Temp\nuget\UiPath.Script.Activities\<some number>.
  3. You may also try making a Packages folder somewhere in your Documents directory, put the packages in there, and configure that as a source.
    Obviously, put your own user name in the path where <yourusername> is, and the actual nupkg filename where <some number> is.
    I have had to try all of these at one time or another to get Script.Activities to install.
