Application Packaging & MSIX
Packaging as a managed service: MSIX conversion, App-V migration, app attach for AVD and a pipeline your team can run.
Checked 4 October 2026. Built from the full service page.
In short: MSIX conversion, App-V migration and app attach, run as a managed service rather than sold to you as a tool. Starts with discovery, because the list of applications genuinely in use is always shorter than the list people believe, and contains several nobody mentioned.
Who this is for
The problem
Ad hoc packaging doesn't scale. Every application becomes a one-off, quality depends on who happened to build it, and there's no way to prove a package will behave the same on the next release. Meanwhile App-V sits on a support clock, the gold image keeps growing because it's easier than packaging properly, and each new starter or new app version reopens the same argument.
What we would do
Start with discovery: the list of applications actually in use is usually shorter than the list people believe and contains several nobody mentioned. Decide per application whether it is repackaged from source, converted, captured or retired, before anyone touches a packaging tool.
- If you still hold working source media, repackage from it. A capture of a running install inherits whatever state that machine was in and needs more testing, not less.
- If the application uses kernel drivers, services, or writes to its own Program Files directory while running, MSIX will not contain it and the answer is a different delivery mechanism.
When we are not the answer: If you have an in-house packaging team with capacity, you do not need us for volume. Where we earn our place is the applications that fail, the ones nobody can package, and the pipeline that stops it becoming manual again.
What is included

- Application testing, remediation and compatibility fixes
- CI/CD packaging pipelines built and handed over to your team
- Legacy capture with EtherApps Forge where installers no longer exist
What the last 12 months looked like
What it costs
Scoped and quoted against your estate rather than sold from a rate card. We price what you already run, including the parts that are working and do not need replacing, and the quote itemises what is included so it can be compared line by line with anyone else’s. Managed IT support starts at £40 per user, per month if that is the wider question.
Three questions people ask
Do all applications convert to MSIX?
No. MSIX runs applications in a container, so anything installing kernel-mode drivers or Windows services, requiring elevation at runtime, installing other applications, hooking deeply into the shell, or writing into its own Program Files directory will either need significant remediation or can't convert at all.
Is App-V really being retired, and what is the end of support date?
The date worth knowing is 14 April 2026, and the detail most summaries get wrong is what it applies to. That date is the end of extended support for the App-V server infrastructure: the Management, Publishing and Reporting servers.
Does every MSIX package need a code-signing certificate?
Yes. Windows will not install an unsigned MSIX.
