DreamHouse app installation fails.

Developer Beginner > Platform Development Basics > Get Started with Salesforce Platform

As indicated in the instruction, I created new Trealhead Playground and tried to install DreamHouse app. Then I encountered a problem. I appreciate if someone can guide me to at where I should look into to resolve the issue.

The installation page
*Choosing "Rename configuraiton ..." option also ended up on the same error screen.

Hi Hashi,

Mostly this could be the issue with the link which is provided to install the unmanaged package.

As there are two links provided to install the Dreamhouse app, may I suggest you please give a try by installing the unmanaged package for summer17 org which should resolve the issue.

Following is the link which worked fine for me.
Still, if the problem persists please let us know so that we can check with the support team on the following issue.

Hope this helps.

Mark this as solved if it's resolved.

Thanks,
Nagendra

Nagendra,

Thank you for the reply.

The apvId was exactly the same with the URL I tried, so I was trying the same package.

However, re-logging in to the environment and selected the already created Playground worked fine with the same setting. I think I should have tried it at least.

Thanks, though!

Regads,

Hello,
I failed the installation; therefore, I tried to follow and copied your link https://na43.lightning.force.com/packagingSetupUI/ipLanding.app?apvId=04tB00000009UeX  and pasted it into my DE environment. The link then became https://na22.lightning.force.com/packagingSetupUI/ipLanding.app?apvId=04tB00000009UeX.  However, I am still unable to install DreamHouse. Please advise.

our request to install package "DreamHouse Summer 2017" was unsuccessful. None of the data or setup information in your salesforce.com organization was affected.

If your install continues to fail, contact Salesforce CRM Support through your normal channels and provide the following information.

For the challange, I installed "Trailhead Tracker" and that worked. The AppExchange search takes you there and the link by the challange also.

I am also having trouble installing Dreamhouse app to complete the hands-on challenge. These are the errors I get:

I have tried all the above suggestions with no luck. When I try to download Trailhead Tracker the AppExchange gets stuck in a loop trying to load the login screen. 

Please help me install this app so I can continue my training.

Hi,

There is no DearHouse app while I try to find it in AppExchange.
I actually try to install "Trailhead Tracker", but it shows below error:

This app can't be installed.
There are problems that prevent this package from being installed.
Insufficient PrivilegesYou do not have the level of access necessary to perform the operation you requested. Please contact the owner of the record or your administrator if access is necessary.

Can anyone help me with this problem?

Thanks,

I had the same problem. I initially signed up with a free 30-day trial account, and I guess those accounts don't come with Apex enabled in the Trailhead Plyaground. I signed up for a new Developer account (free), linked it to my first account, and switched the Trailhead playground to the Developer's as default. Then I tried the installation again and it worked!
Pamela BethanyPamela Bethany
I had the same issue not being able to download the dreamhouse app. I resolved it by doing the following. This is for people who also have the 30 day trial along with the Trailhead playground.
1. I have a 30 day free trial with a username and a playground with a different username.
2. When you click the link to install dreamhouse (from the challenge box) is will take you to the window that displays the the boxes to select all users.
3. LOOK at the address in the browser. It should be your playground username, NOT your 30 day trial username.      
4. Replace your 30 day trial username with your playground username. It will then download and you can pass the challenge.
5. Replace the address as in this example -------------https://insert your playground username here-dev-ed.lightning.force.com/.............

I had a smiliar issue. There was a existing object Properties which had API name property__c. After renaming the API name, app got successfully installed.

I had similar issue Ana: I tried in another playground and another error message : "Dreamhouse already installed"... and yes, it was installed in my TP1...
Paul LambertPaul Lambert
I had similar issues, which I believe occured since I had completed other modules prior to this one that required me to create these objects. I manually renamed the Property object to PropertyV1 and Favorite to Favourite (since I'm Canadian :) ) and the package installed without any further issues.

Similar - just read the error message.  There's a type called Property which has an api name that clashes.  If you do an earlier trailhead module it gets you to create this so you need to delete or rename before you can do this one..

Hi,

Anyone facing following error:

Duplicate NameThe name "Property__c" is already used on component type: Custom Object Definition. Please rename existing component.
Duplicate NameThe name "Property__c" is already used on component type: Custom Tab Definition. Please rename existing component.


Solution:
This is caused because you might have completed a trailhead on creating fields in Salesforce before trying this trailhead. In the Field creation Trail head you might have created an custom object named Property. So by default the API name of that object gets named to "Property__c". Just look for that custom object and edit the API name to anything other than "Property__c". And run the install again.

Voila!

I couldn't find the Package ID itself and finally copied it from this page.

When creating an object I too bumped into the same error Duplicate name for Property... I simply went back, created again with a changed spelling to Properti. 

This works too...

you will probably spend most of your time in the writing phase; on the other hand, for a reasoned college-level essay, you will need to spend more time researching your topic and developing an essay writer (https://handmadewriting.com/original argument before you start writing.
