ComStudy 2.2 Requirements

Operation System

ComStudy is designed for Microsoft Windows. Supported Windows platforms are:

  •     Windows 98
  •     Windows NT 3.5 and 4.0
  •     Windows ME (Supported though not recommended)
  •     Windows 2000 (all versions)
  •     Windows XP (all versions)
  •     Windows Vista (all versions - As of*
  •     Windows 7 (all versions - As of*


Must be a minimum of 128 MB. If you plan to perform detailed studies with many transmitters, we suggest 512 MB.

Disk Space

Recommended 1 - 3 GB for installation of program, terrain, databases, & data files.


Should be at least 17" (diagonal). The video resolution required in 1024 x 768 (minimum) at 16 bit color. If space is not a factor, ComStudy will benefit from having two monitors available (one for text and one for maps). We have found this mode (which is supported by all above Windows versions) instantly addictive.


Processor speed should be at least 200 MHz. We recommend 1 GHz and above for faster calculation times, and prefer AMD over Intel for its improved floating point computational speed.

Internet Connection

Required for downloading program and database updates. Also used with non-standard ports for access to RadioSoft's online databases. In order to keep the client's network secure, only outgoing TCP connections to our servers will be necessary to open through a firewall or proxy server.

Windows Vista / Windows 7

While ComStudy is compatible with both Windows 7 and Vista, , it does require rights to the HKLM registry hive. This means that the program needs to run as Administrator. As Windows Vista and 7 run Administrator accounts at the user level, you must force this setting by right-clicking on the ComStudy icon, going to Properties, then the Compatibility tab, then checking the box at the bottom to “Run As Administrator”. You can also skip this step by disabling UAC in Windows.


Note that any ComStudy disc produced after mid-2008 does the above for you.
