Fast QVD viewer


The application is offered "as is", without warranties and liabilities. You may not resell it, disassemble or offer it under a different branding.

The free version is limited to 50'000 100'000 rows. If a QVD file has more rows then only the first 100'000 will be loaded. Filtering and counts will be limited to only the loaded rows. To get the full version purchase a license.

Update from ver.2 to ver.3

Version 3 requires a new license key. License keys for older versions don't work with version 3. Keys issued after August 1st, 2015 are eligible for a free update (see Release notes for more details). Keys issued before August 1st, 2015 are updated at 50% of the regular price.

Known issues and limitations

  • First launch can take a bit longer than normal. Subsequent launches are instant.
  • On some versions of Windows the installer doesn't associate QViewer with .qvd file extension automatically. Make such association manually, if needed.

Virus or malware alerts

Some corporate web screens block all shortened URLs like the download links on this page. In such case use these direct links: 64-bit, 32-bit.

QViewer is routinely checked for malware. Although some antiviruses may give false positive warnings. If you get such warning please check the size of downloaded archive. Let me know if it's noticeably larger than indicated in the download link (see my email in my blog). The installer is signed with a code signing certificate issued to EasyMorph Inc.
