maximum size to encrypt/decrypt

I am using 2.2.2 version and am only able to decrypt 1.25Gb of data after encrypted using GpgEX. I have tried decrypting several tar files which encrypted successfully but I get an error

Microsoft Visual C+++ Runtime Library. What is the maximun size supported?

The folder/file combined size which failed are 2.57.Gb, 3.38Gb, 19.4 Gb and 46.4 Gb
