Citrix is sever, desktop virtualization, networking and cloud computing software application. Citrix uses Independent Computing Architecture protocol for data passing between the server and client.
For configuring the protocol between the two is defined by a configuration file which is given the extension of ICA. The working mechanism of ICA is similar to Windows server. Some other server applications also use ICA protocol and hence use ICA files to transmit data between server and client. ICA usually runs over TCP port 1494. In some cases it uses CGP protocol as base protocol. All these configuration settings are mentioned in ICA file.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .ICA file, there may be several reasons that cause problems with opening and operation of the data format:
A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .ICA file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .ICA file, so download the update and check again.
If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:
It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
There may be several reasons why you cannot open the file with .ICA extension. Directly on this website you can find a solution of the most common problem with the .ICA file – that you do not have on your computer the appropriate program to open the file.
