Solution: Your administrator has blocked this application because it potentially poses a security risk to your computer

The Problem: Your administrator has blocked this application…

You’re trying to install a ClickOnce application and get an error message saying: “Your administrator has blocked this application because it potentially poses a security risk to your computer”:
Your administrator has blocked this application because it potentially poses a security risk to your computer

You are the administrator and don’t remember blocking any applications (if you’re not the admin, contact them instead of reading this article).

The reason this is happening

The ClickOnce trust prompt is disabled on your operating system, so instead of a dialog (prompt) which allows you to either proceed with the installation or not, you just get the message above.

The solution

You can change the ClickOnce trust prompt behavior by editing the registry subkeys under:

\HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\.NETFramework\Security\TrustManager\PromptingLevel

There should be five subkeys, one for each security zone:
Registry trustmanager promptinglevel

Each subkey can have one of the following values:

  • Disabled: No trust prompt is shown, instead you get the error message above.
  • Enabled: A trust prompt is shown.
  • AuthenticodeRequired: A trust prompt is shown only for signed applications (other applications cannot be installed).

Trust prompt example

If the application you’re trying to install has been published on the Internet, you’ll want to set the Internet subkey to “Enabled” (or to “AuthenticodeRequired” if the applicationt has been digitally signed). You should then see a trust prompt instead of the “your administrator has blocked this application” error:
Trust Prompt - do you want to install this application

Free Trust Prompt Tool

As an alternative to editing the registry manually, you can also use a free trust prompt tool I wrote:
Trust Prompt Tool

It allows you to easily display and modify the trust prompt configuration.

Notes:

  • If you don’t trust yourself or other people using your PC, you can change the respective zone setting back to “Disabled” after installing the ClickOnce application. The trust prompt configuration has no effect on installed applications and their updates.
  • You could also add the publisher’s site to your trusted sites and only enable trust prompts for the TrustedSites subkey.
  • Are you wondering why all your trust prompt settings have been changed to “Disabled”? Unfortunately, I have no idea. I’ve had this happen on multiple PCs and I’m pretty sure I didn’t do this myself.

Solution: Windows 10 uses two display languages (at once)

When taking screenshots for a tutorial on how to connect a scale to a network, I came across this curious mixture of both English and German in the network adapter settings:Network adapter properties in German and English

I confirmed that the Windows display language was set to English. I tried  deleting the German language pack, but it did not make a difference: my Windows was still bilingual.

Eventually, I found the solution :

  1. Open to the (legacy) Control Panel, click on Clock, Language and Region, then click on Region.
  2. In the Region dialog, select the Administrative tab.
  3. Click on Copy settings…
  4. You’ll probably see that the Display Language under Current User is not the same as the Display Language under Welcome screen:windows welcome screen and user account settings
  5. This can be fixed by checking the Copy your current settings to: Welcome screen and system accounts checkbox, then clicking on OK:
    windows welcome screen and user account settings monolingual

After restarting, the dialog appeared completely in English:network adapter properties in english

How to use a Transferwise borderless account to get paid by FastSpring

We use FastSpring to sell our software, which means that our account balance is in USD. FastSpring can pay out in EUR to a SEPA bank account, but new FinTech companies seem to offer better exchange rates.

Transferwise is one of these companies. Their bordereless account (which is not the same as their regular account) makes it possible to get paid by FastSpring to a US bank in USD (for free), convert the payment into EUR at Transferwise’s advantageous rates and withdraw it to a EUR account.

1. Sign up for a Transferwise borderless account

Click here and apply (this should direct you to the borderless signup page). You can also click on this affiliate link to get a free transfer and to support this blog, but please note that this will send you to the regular Transferwise signup page.

It took quite a while for Transferwise to open our borderless account. If you don’t hear from them within a few business days, I recommend logging in to check if further documents are required.

2. Activate USD as a currency and get your bank details

Transferwise activate currency

After logging in to your borderless account, you’ll be able to activate currencies. Obviously, you’ll need USD to get paid by FastSpring. Activating USD as a currency also gives you your USD bank details.

I strongly recommend clicking on the “How do I use these?” link to learn more about using your USD bank details.

3. Enter your bank details in your FastSpring account

Things get a bit more difficult here. In your FastSpring account, go to “Payment Methods”, set the bank country to “United States” and click on “Enter Direct Deposit (ACH) Information”:

 

FastSpring payment methods
Note that these are the instructions for FastSpring’s “Classic Springboard”, things will look different if you’re using the more recent “contextual” dashboard.

Transferwise gives you all the bank details you’ll need to enter with the exception of the bank’s name. However, you can easily find the name by either entering your wire routing number (a.k.a ABA routing number) on this website or by entering your ACH routing number here. In our case, both numbers returned “Community Federal Savings Bank” as the bank’s name.

To make things more confusing, FastSpring asks for a “Routing / ABA (9 digits)” number. Do not actually enter the wire routing number (a.k.a ABA routing number) here! Instead, enter the ACH routing number (FastSpring customer support has confirmed that this is correct).

Transferwise recommends choosing “checking” and not “savings” as the account type, so I selected “Business checking”.

4. Add your EUR bank account to Transferwise

Transferwise will notify you when you’ve received a new payment. In order to withdraw it, you first have to add a bank account:

Transferwise add EUR account

5. Convert and withdraw your money in EUR

You can then convert your USD to EUR and send them to your account in one step:

Transferwise send money

Transferwise will show you the exchange rate and the fees (1% for USD to EUR). Soon afterwards (on the next business day in our case), your money will show up in your EUR bank account.
