Solution Found=Camstudio Windows7-64 bit- Lossless Compression Not Showing Up!

  I found a solution to that problem. It is a 64-bits issue. 
  
  1. Install codec normally (if not done yet). 
  2. Extract the codec archive, and copy this file "camcodec.dll" to this location: "c:\Windows\SysWOW64". You will need administrator rights (Windows will prompt you). 
  3. Start or restart Camstudio, or any other video program, and check if codec is visible now. 
  
  If it is not sufficient, you can try to make some registry changes: 
  
  

  Create a pure text file, using Notepad. 
  Go to run and type in "regedit"

  Create  

  
  [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\drivers.desc] 
  
  

  right click to menu, create a new string value, copy 

  "camcodec.dll"="CamStudio lossless codec [CSCD]" 

  

  
  

  [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Drivers32] 

  "VIDC.CSCD"="camcodec.dll"  

  
  right click to menu, create a new string value, copy VIDC.CSCD

  and copy into the field called value data: camcodec.dll

  
  

  
  

  
  

  
  

  
  Then open (run) the file. 
  You will need administrator rights (for example, run Regedit in administrator mode and import the text file in it). 
  Finally restart camstudio. 
  
  I hope that will help. 
  Maybe the codec creator will fix the installer.

  I followed each of the steps moisamva gave in June and they work flawlessly with Windows 7 64 bit. The lossless codec now shows under the options ---> Video options --- Compressor list. These instant solutions are recommended to everyone.
