    Adobe Reader X - strange behavior at failed instalation


      I do not remember if I have ever any problems with installation of the Adobe Reader since I guess version 5 or 6.

      But I am not able to install Adobe Reader X at all, using Adobe Reader 9.4.x on Vista64 Home Premium SP2.


      I use Avast Free AV and Comodo CIS without AV.

      Initially I did not turned them off as it was not ever needed.


      I have I guess twice or 3 times downloaded install_reader10_cz_mssd_aih.exe   30 kB online setup file.

      After launching it under alevated admin privilage ( normally working on limited account ) the strange things started to happen.

      Process Explorer showed the new and new processes arising,

      adding endless chain of "_1" suffixes to original install_reader10_cz_mssd_aih name.


      After killing I realize, the original setup exe file from the download storage disappeared.

      In the TEMP folder there was left file install_reader10_cz_mssd_aih_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_ 1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_ 1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1_1.exe

      of the same size ( 730 kB )


      No setup GUI or dialog windows appears, no error is raised.


      Interesting thing is the same happens if I try to install Adobe Flash player online by elevated Firefox.   (  install_flashplayer11x32_mssd_aih_1_1_1_1_1_1_1_1_1_1_1.exe   )

      If I use my usual way by downloading setup from here   fpdownload.adobe.com/get/flashplayer/current/install_flash_player.exe

      everything does well.


      The same above happened when I switched OFF on access scanners of AV, and FW and HIPS features of the Comodo CIS.

      Regular Avast AV checks and SuperAntimalware/MBAM checks did not shown in last years any active infection.

      No similar problems with instalation of other software.
