<title>Unable To Install Multichain Enterprise In Windows 10.</title>
<link>https://www.multichain.com/qa/53680/unable-to-install-multichain-enterprise-in-windows-10</link>
<description>Hello everyone. I hope you're all doing well. I'm posting this to fill a void. When I try to install &amp;quot;Multichain Enterprise&amp;quot; on my Windows 10 PC, I get an error notice that says &amp;quot;problem opening file for writing.&amp;quot; I'm not sure why this is happening or how to resolve the problem. I did everything I could think of (a fresh install, rebooting the computer, disabling the antivirus, etc.) but couldn't find the problem. Is there anyone who can assist me in resolving this issue? Any ideas would be greatly appreciated.</description>

<title>protocol upgrade</title>
<link>https://www.multichain.com/qa/9920/protocol-upgrade</link>
<description>&lt;p&gt;I have some questions regarding using the Multichain software. We have downloaded the version 1.0.4 version of Multichain and have made a new chain. We are attempting to upgrade the protocol of this chain to 20002 from 10010 using the instructions written on &lt;a rel=&quot;nofollow&quot; href=&quot;https://www.multichain.com/developers/upgrading-nodes-chains/&quot;&gt;https://www.multichain.com/developers/upgrading-nodes-chains/&lt;/a&gt;. During the upgrade process (after step 3 to be exact), an error pops up like below:&lt;/p&gt;&lt;p&gt;error code: -8&lt;/p&gt;&lt;p&gt;error message:&lt;/p&gt;&lt;p&gt;Invalid protocol version, cannot upgrade to future version&lt;/p&gt;&lt;p&gt;So we downloaded the 2.0 alpha 2 version of the software, and proceeded to run the same chain using the 2.0 alpha 2 version instead of the 1.0.4 version, only to be met with another error&lt;/p&gt;&lt;p&gt;ERROR: Parameter set for blockchain kaitest was generated by MultiChain running newer protocol version (10010) Please upgrade MultiChain&lt;/p&gt;&lt;p&gt;So, to summarize, how can we upgrade the protocol of our blockchain from 10010 to 20002 without encountering such errors above?&lt;/p&gt;</description>
