Description

How to reproduce

  1. Download https://downloads.adblockplus.org/adblockplusie-1.2-x64.msi
  2. Note the file size (4.558.848 bytes).
  3. Now compress that file, e.g. via gzip adblockplusie-1.2-x64.msi
  4. Look at the file size of the compressed file.

Observed behaviour

The size of the compressed file is 3.218.239 bytes, roughly 70% of the original size. This indicates that the compression of our MSI file is very suboptimal - if it is compressed at all.

Expected behaviour

The size of the compressed file should only be minimally smaller, if at all. Note that adblockplusie-1.2.exe apparently applies additional compression - gzip almost doesn't compress it, and its size is only minimally larger than the two MSI files after they have been compressed by gzip.
