Failed to upgrade or install Open Live Writer 0.6.2.0 on Windows 8.1

I use Open Live Writer (OLW) since version 0.5 (actually is 0.5.1.2 - It is the second release of OLW and also the first release support Blogger)

It is a tools for me to write my blog on blogger after the Windows Live Writer 2012 end of life.

Since the apps is auto upgrade every time you open it. It will auto upgrade to the latest version.

But it seems that it cannot upgrade from 0.5 to 0.6 via this progress. And also, my OLW suddenly did not able to open today.

Event 1026, .NET Runtime

Event 1000, Application Error

I try to upgrade to 0.6.2.0 manually, I failed.

After I do some Google, I suspect it is because my Windows 8.1 did not install .Net framework 4.6.2

I download the .Net framework 4.6.2 offline installer (https://www.microsoft.com/en-us/download/details.aspx?id=53344) and install it. After that, I also apply the latest security hotfix for 4.6.2 via Windows Update

After I upgrade my .Net framework to 4.6.2, I able to upgrade my OLW to 0.6.2.0 now

3. Copy all files under "C:\ProgramData\Microsoft\Windows\Hyper-V" to the same location of the new Windows 10 machine

4. Run the PowerShell to change the permission of those VM (If you miss this step, you will receive a error (Fig.1))

5. Start the hyper-V service

6. Done (You will able to power on those VM on the new host)

If you receive a error message (Ethernet Port....) like the following when you power on a VM:

It should be the Virtual Switch configuration is different between the old host and the new host, change the virtual switch selection on the VM will fix the problem.

Change to the new host configuration:

WMP EHCT801 WiFi not stable after upgrade to Windows 10 (1703) Creators Update

If you hit the issue on WMP EHCT801 WiFi not stable (Always disconnected suddenly and randomly) after upgrade to Windows 10 (1703) Creators Update. You need to check your Wireless card driver version.

I hit this issue when I using 3008.30.315.2016

After I upgrade to 3008.33.430.2016, the issue resolved.

It seems that we need to upgrade the Realtek RTL8723BS driver to 3008.33.430.2016 when running on Windows 10 1703 Creators Update.

Download the driver:

CloudReady based on Google Chromium OS and also free for home use

One of the requirement to running CloudReady is your machine support UEFI boot, since the IBM X61 did not support UEFI boot, so I install Lubuntu on it.

For the CloudReady, I use the Lenovo X200 which is able to install the CloudReady.
