Script via Plink in .bat behaves differently

I have a .bat file on my Windows machine. This .bat file uses plink.exe to connect to an Ubuntu machine and execute an .sh script. However, I get different behaviors on the script depending on how Plink is used:

1. log onto Ubuntu directly (in person) -- script succeeds

2. ssh via Bitvise client -- script succeeds

3. ssh via Plink (by calling plink.exe) and calling script from interactive shell (it's a Ubuntu shell within windows cmd.exe) -- script succeeds

4. ssh via .bat which then calls Plink -- script fails

The script fails w/ message:

error while loading shared libraries: libCint.so: cannot open shared object file: No such file or directory

Other posts seem to refer to installation/permission issues of libCint.so but I know this is not the case since the script works correctly in other instances as shown above.

Below is the plink.exe line from my .bat file:

plink.exe !plink_ssh_details! myscript

The above script fails when called this way via .bat file; again, note that it succeeds when called directly from the Ubuntu or when I -ssh directly into the Ubuntu via cmd.exe (using plink.exe) or Bitvise client. Any help would be appreciated.
