AppV 5.1 HF3 is available for public download

Posted on

Recently Simon Dettling wrote an article about this hotfix & you can find it HERE. At that moment this was available on demand[May have to request Microsoft to get that]. Now it is available for public download.

Microsoft recently released “April 2016 hotfix rollup for Microsoft Desktop Optimization Pack” which includes HF02 for UEV 2.1 & HF03 for AppV 5.1. This HF03 for AppV 5.1 fixes issues such as App-V crashes on (RDS) when dynamic configuration causes a policy update, Custom configurations for existing entitlements are overwritten, added ETW log to detect when file has incorrect “FILE_EXECUTE” permissions & App-V template for UE-V is missing registry keys.

You can find it HERE.

Make sure to restart the machine once you apply hotfix.


Enable-AppV PoSH in Build 14316

Posted on

As you all know that Microsoft stated that they are including AppV Client into the core OS & they are making this in Redstone 1[An update to Windows 10] which will be made available this summer.

So, Microsoft recently released a Build 14316[Windows Insider Program] where we see that AppV Client & UEV Client is already part of it. I recently wrote about that HERE in which I’ve stated that I do not see an option to turn on AppV Client which is disabled by default. So I turned on AppV Client service & published an application.

This is to let you all about the PoSH command available by which we can turn on/off AppV Client. You first have to change the execution policy, import AppV Client & then use Enable-AppV which will automatically start the AppV Client service.


If you wish to disable AppV Client then use Disable-AppV. Please note that these commands will not work if you start/stop AppV Client Service manually.

Even after enabling AppV Client using Enable-AppV, I am still not able to run standalone msi which we have got as out from sequencer. The error says that Application Virtualization Client version 5.0 or above needs to be installed to install this product.


AppV Client Install on Build 14316

Posted on

I’ve tried to Install AppV 5.1 Client & Sequencer on the VM that I’ve created using Build 14316. I’ve got the window below when I executed AppV Client Setup.

AppV 5.1 Client Build 14316

As a test I gave a try with the older version of AppV 5[5.0 sp2] & the behaviour is same. There seems to be a logic to restrict Installation of AppV 5 Client. I’ve mentioned this in specific to AppV 5 because I was able to Install AppV 4.6 Client Successfully.


AppV 5 Client in Build 14316

Posted on Updated on

Today I’ve built a VM with Build 14316[Windows 10 Insider Preview Program] & I see that Microsoft made AppV Client part of OS. Have seen if there is anything available to turn the feature on. But, I didn’t find any. 14316

I see that the AppV Client Service is disabled. What I did is just enabled the service & published a package using PoSH which seems working. I did try to install the standalone msi & have got an error as below,


Seems that there is something which Microsoft has not included in this build because in the previous build I just found AppV Logs & in this they included AppV Client [Services, Files & so]. Assume that they are doing it in a step by step manner. Let’s see what we get in the next version.

AppV 5.1 & Java Max Heap Size

Posted on

There seems an issue with the AppV 5.1 & Java applications which has custom heap size. As the sources this seems only with 5.1 & downgrading to SP2 or SP3 resolved the issue.

Please note that this is a known issue & Microsoft is working on it which we can expect as a hot-fix soon.
