Frequently Asked Questions (FAQ)

Winflector - general

Expand..Which applications can be shared using Winflector?

Any 32/64-bit Windows application, including console applications can be shared using Winflector server. Applications designated for sharing must be registered on the server. Once registered they will be accessible to any authorized user for remote execution from the client station.

Expand..Does the application code need to be modified?

No – applications shared by Winflector server do not require any modification. Each application which is available as an executable program can be shared.

The application code can be modified, if necessary, for instance to transfer some operations onto the client workstation. A typical example is the handling of a fiscal printer.

Expand..What are the parts of Winflector software?

The Winflector package consists of three parts:

  • Winflector server – used to start and supervise applications.
  • Winflector client – a small program which connects to the server and transmits information on what application is to be executed.
  • Optional programming tools to be used in the application for advanced communication between the application and the client.

Expand..What are the benefits of sharing applications using Winflector?

Most important benefits include:

  • centralized processing
  • better application access (from any place in the network)
  • significantly lower costs of application sharing and centralized system administration
  • minimum system requirements for client workstations
  • small network traffic between the application and the terminal – efficient execution over wide area network
  • better work quality without any modification of the application code
  • increased data security in a centralized system

Expand..Can I test my application for more than two users?

Yes. We will provide a time limited trial version of the Winflector software for the requested number of users for testing. Please contact us via email ( or using the contact form.

Expand..How to check Winflector version and where to find diagnostic information?

Winflector server version can be read on the server (wfserver.exe) from the 'About Winflector' window (right mouse button click on the window frame), see the 'Product version' field.

The currently installed client version can be read in the client installation – the gte directory contains gtexxxx subdirectories, where xxxx is the version number. The Winflector client (wfc.exe) connecting to the server will start the appropriate version of the software. If such a version has not been installed it will be downloaded from the server.

Diagnostic information from the server is saved to trmactiv.log, trmexcpt.log, trmlogin.log and tapplog.txt files in the applogs subdirectory of the server installation.

Diagnostic information from the client is saved in the tcllog.txt file in the logs subdirectory of the client installation.

Expand..How to get technical support?

Technical support for commercial users is available via e-mail (

Technical support for free version users is not guaranteed, nevertheless, if you encounter a problem we kindly ask you to report it. Technical problems can be reported using the report problem form or (after registering) on the users forum (Technical support).

When reporting a problem we kindly ask you to provide the following information:

  • name and version of the software, license number
  • server and client operating system (exact version including patches)
  • a detailed error description, frequency of its occurrence, information if the error can be reproduced
  • can the application which caused the problem be made available for testing in our laboratory

Expand..How does the automatic client update work?

Automatic client update takes place when the client connects to the Winflector server. If required, a new version of the client software is downloaded from the server. In this manner, it is sufficient to install new software on the server computer, no manual software update needs to be done on the client stations. The update process runs as follows:

  • Winflector client wfc.exe program executes the most recent version of the vtm.exe program which is available on the client to connect to the server.
  • The server sends data which identifies the client software that will work together with the current server version.
  • The identification data is compared to that of the software on the client workstation. If the identification agrees, the update procedure at this time is over.
  • If the identification data sent from the server is different from that of the client, the new client software is downloaded from the server to the client computer and saved in the proper directory. After a successful update the proper version of the client software is started. The whole process runs transparently to the user.

The automatic update procedure works for both more recent and older versions. If a client station has Winflector 3.5 software it can download and update the client 3.0 as well as the client 4.0 version.

Automatic client update method can be used to distribute additional user files to client stations – more information about this feature can be found in the documentation.

Rozwiń..What to configure to work over the Internet

To allow a workstation connected to the Internet  (Winflector client) to work with Winflector server installed on a computer in a local network and having a private IP address in this network one need:

  • on the router having a public IP address redirect the TCP port 6601 to the port 6601 and IP address of the computer with Winflector server,
  • on the workstation (client) set the public addres of the router as a Winflector server address.

It is shown on a figure below:

In the above configuration you specify and port 6601 (default) as a Winflector address.

If for some reason the redirection of the port 6601 on the router is not possible, you can redirect another port router (e.g. 6602) to the port 6601 of Winflector server, but then on the client workstation, change the default port number (6601), to the port number redirected on the router (e.g. 6602).

Below: the configuration with 2 Winflector servers.
