FlexPlan (Filemaker Pro) stops with error 0x06d007e after XenApp 5 HRP6

FlexPlanAfter upgrading a Citrix XenApp 5 farm with Hotfix Rollup Pack 6 (HRP6) and Internet Explorer 6 to Internet Explorer 8, the FlexPlan application (which uses Filemaker Pro) was unusable. The application is virtualized using Microsoft App-V, so the system administrators had some difficulties troubleshooting the application.

Users launching the application saw the App-V progressbar loading the application.

And a few seconds later receiving an message that the application is closed, without seeing any applicaion on the screen.

Closing FileMaker Pro

Since the users noticed that IE6 was upgraded tot IE8, they assumed that was the problem. When the Flexplan application was launched by an Administrator, the application does work. So the second though was a permission problem.

Smartcard not working on Windows CE 6 thin client (Citrix XenApp 5)

Begin this year a customer asked me to solve his problems with smartcards (UZI-pas) on Windows CE6-based thin clients. The problem was, in short, that after removing the smartcard it was unrecognized.


As a bonus, when a user was authenticated using a certificate on the smartcard, an eject and reinsert was simulated causing the problem to raise instantly. Since the customer has over 2000 thin clients, this is a major issue.

During some investigations I found out that the problem did not occur with the Win32 client, only with the CE6 client. So one solution could be to replace all thin client  with a Windows Embedded version since this is a Win32 platform. As you can imagine, no customer is happy to hear this as a “solution”.

Citrix Synergy starts tomorrow in San Francisco. From wednesday 12 may till friday 14 may all updates, new features and other news is presented to the public. One thing that’s excites me most is the upcoming XenClient, a baremetal hypervisor.

Combined with a VDI solution like XenDesktop the XenClients enables the customer to take the VM outside the datacenter en get it onto his desktop / laptop using his local resources. Altough this sounds a bit like we were used to work, and in fact it is, there is a big difference.

In the Citrix ICA client, or XenApp Client Online plug-in, the access to your client drives is protected.
The first time you access your client drives the client will ask to allow (or disallow) the access. This message looks like this:
